4.1 Contract Types and Required Elements

Contract Types and Required Elements

A contract is a legally enforceable agreement between competent parties to do or refrain from doing a legal act, supported by consideration. Real estate practice runs on contracts—listing agreements, buyer-representation agreements, purchase contracts, options, leases, and escrow instructions—so the national exam tests both classification and the elements that make an agreement enforceable.

Classifying contracts

The exam loves classification pairs. Learn them as opposites:

An option contract is the classic unilateral trap: the optionor (seller) promises to keep an offer open; the optionee (buyer) pays for that right but is not obligated to buy. It becomes bilateral only when the optionee exercises the option.

The five essential elements

1. Offer and acceptance (mutual assent / "meeting of the minds"). A definite offer accepted without material change. Any change in terms is a counteroffer, which rejects and terminates the original offer.
2. Consideration. Something of legal value exchanged—money, a promise, or forbearance. Earnest money is evidence of consideration but is not legally required to form the contract.
3. Capacity. Parties must be of legal age and sound mind. Contracts with minors and the mentally incompetent are generally voidable by the protected party.
4. Legal purpose (legality of object). The objective must be lawful; a contract to violate fair-housing law is void.
5. In writing (for real estate). The Statute of Frauds requires sale and long-term lease contracts to be written and signed.

Void, voidable, unenforceable

• Void: no legal effect from the start (illegal purpose, missing essential element).
• Voidable: valid until the injured party disaffirms (minor, fraud, duress, undue influence, misrepresentation).
• Unenforceable: valid between the parties but a court will not enforce it—e.g., an oral land-sale contract or one past the statute of limitations.

A quick numeric trap: an offer states "$310,000, close in 30 days." The seller signs but writes "$315,000." That signature is not acceptance—it is a counteroffer of $315,000, and the original $310,000 offer is dead. The buyer is now free to accept, reject, or counter again.

Statute of Frauds and "the party to be charged"

The Statute of Frauds requires that contracts for the sale of real estate, and leases for more than one year, be (1) in writing and (2) signed by the party to be charged (the party against whom enforcement is sought). A buyer suing a seller needs the seller's signature; the buyer's own missing signature does not necessarily bar the claim.

Exception—part performance: A court may enforce an oral land contract if the buyer has paid, taken possession, and made improvements, because those acts show a contract existed.

Time of the essence

Unless the contract states "time is of the essence" (or the parties' conduct makes it so), a reasonable delay in performance is usually not a breach. When the clause is present, missing a deadline—closing on day 31 when day 30 was required—is a material breach.

Worked example: A lease runs 18 months and is oral. Because it exceeds one year, the Statute of Frauds makes it unenforceable as written for the full term; many courts will treat it as a month-to-month tenancy instead. A 12-month oral lease, by contrast, falls at the one-year boundary and is generally enforceable.

Reality of consent: when assent is defective

Even with offer, acceptance, and consideration, a contract is voidable if genuine assent is missing. Five defects recur on the exam:

• Fraud — an intentional false statement of material fact relied upon; the victim may rescind and sue for damages.
• Misrepresentation — an innocent or negligent false statement; the victim may usually rescind.
• Mistake — a mutual mistake about a material fact can void the contract; a one-sided (unilateral) mistake usually does not.
• Duress — assent forced by threat.
• Undue influence — improper pressure by someone in a position of trust (a caregiver over an elderly seller).

Trap: Fraud makes a contract voidable by the injured party, not automatically void. The defrauded party chooses whether to rescind or affirm; the wrongdoer cannot use his own fraud to escape the deal.

Counteroffers, the mailbox rule, and electronic signatures

Formation timing decides many questions. A counteroffer rejects and terminates the original offer; the original offeror is now the offeree and may accept, reject, or counter again. Once rejected, an offer cannot be revived by simply trying to "accept" it later.

Under the common-law mailbox rule, an acceptance is effective when dispatched (mailed), but a revocation is effective only when received. Modern real estate contracts usually require acceptance to be delivered to be effective, overriding the mailbox rule by their terms.

Worked timing example: Seller offers at $300,000, good until Friday. Thursday the buyer mails a counter at $295,000 — this kills the $300,000 offer. Friday the buyer changes his mind and tries to accept the original $300,000. There is no contract: the counteroffer already terminated the original, so the seller is free to walk or re-offer. The federal E-SIGN Act and state UETA make electronic signatures and records as valid as ink for real estate contracts, so a contract formed by email or e-signature platform is enforceable.
